High school transcripts

I can’t seem to find an answer to this anywhere and I probably sound so stupid asking this but when I apply to college/university do I have to provide transcripts from all four years of high school? I’m asking because I’m 9th grade I went to public school and I did absolutely horrible so half way through 10th grade (same school) I decided to do homeschool. I didn’t go to the public school long enough to get any actual transcript for 10th grade. 11th grade I decided to go back to public school but this time I went to a different school. Now I’m being homeschooled again. So basically my transcript just jumps from 9th grade to 11th grade, and then I have my home school transcript that has some 10th and now 12th. So do I send in like 3 different transcripts and how do I even get the transcripts from my other schools I don’t know I’m so confused on how this works
